1. Idenity Function: f(x) = x Chemistry. A representation of a chemical reaction, usually written as a linear array in which the symbols and quantities of the reactants are separated from those of the products by an equal sign, an arrow, or a set of opposing arrows. http://www.answers.com/topic/equation#ixzz1cITv2Mkh
2. Square Function: f(x) = x^2
3. Cube Function: f(x) = x^3
Cubic functions can be used to model real world data, like container measurements or magnetic energy models.
